The “Mean Girls” actress jetted to the South American country on Wednesday as part of a deal to help promote a Brazilian clothing label.

She is due to begin a 90-day stint in a lockdown rehab center in the U.S. to address her issues as punishment for lying to police over a car crash in California last year, but she enjoyed a wild night out in Sao Paulo shortly after landing in Brazil.

An image obtained by editors at TMZ.com depicts a sweaty faced Lohan sitting underneath a table in a nightclub while wearing designer heels and a short black dress.

A report on a local website alleges the actress was hiding from onlookers after being besieged by fans wanting to take photos with her.
